Abstract

A data protection policy is implemented on a computing device, the data protection policy indicating how organization data on the computing device is to be protected. Protection of the organization data includes encrypting the organization data, and allowing the organization data to be decrypted only by particular programs and/or under particular circumstances (as indicated by the data protection policy). When implementing a data protection policy, files already stored on the computing device are encrypted using a passive encryption technique. The passive encryption technique can include one or more of an encrypt on close technique, an encrypt on open technique, an encrypt without exclusive access technique, and an encrypt location technique.
